Dear Mark, Littonia is a summer rainfall South African. I grow mine much like Gloriosa and it behaves much the same. For me in Coastal Northern California with heavy rainfall in winter and cool summers that means that I leave it in the greenhouse in its pot, mostly dry during winter dormancy so I cannot attest to its hardiness. In the spring I start watering again and it comes up about a month later. It is a robust climber so needs support and a large container. Right now mine plant has yellowing leaves and seed pods and is ready to be left for the winter. Rob Hamilton grows it in Australia and contributed photos to our wiki page: http://pacificbulbsociety.org/pbswiki/index.php/… I think Cathy Craig grows it in Southern California. I am quite fond of my plant which just appeared one year, no doubt a result of my reusing the soil when seeds I had sown never came up and I gave up on them. I've not had a lot of luck with seeds of Littonia and Gloriosa, but maybe wasn't patient enough. Angelo translated a very interesting article on Gloriosa for the ABA journal and maybe he could speak to how to germinate these seeds. I haven't tried Littonia outside because my experiments with Gloriosa outside haven't been successful although I know others have different experiences. Rachel told me that Gloriosa could tolerate winter rainfall in Cape Town, but the ones I planted out never made it. I put a pot on my deck one summer and between the wind and the fog those plants looked so unhappy that I finally moved them to the greenhouse where I had another pot that looked so much better. When I lived in Stockton where I had hot summers they were quite happy in a pot outside. My husband tied strings this year from the ceiling of the greenhouse for my Littonia, Gloriosa superba, and Sandersonia aurantiaca to grow on and the Littonia and Gloriosa were soon blooming way up there. I would have needed to get a chair to stand on to photograph them. What supports do others use for climbing plants? I hope this helps. Mary Sue
